I have 2 broodies they had 2 nest boxes the both liked and would take turns at. At one point, they fought over nests and broke the eggs. I waited a few days and they were both still sitting in separate nests but no eggs to fight over. I took a cloth and covered one of the nest boxes.the hen in that box I can catch she is friendly,I will let her out in the morning 15 min then put her back.. . the other box I left open to the independent grumpier hen. When I was covering the nice hen's area, grumpy got mad at me, then when she could see I was giving eggs to the nice hen she got even more upset, then I put some eggs in her nest box, she could see the eggs and went to sit. I hope all will be well now!
